Lifeblood of the Grid

Posted by wastedenergy on February 28, 2010

Most people believe there are substitutes to be found for the raw materials out of which civilization is built.  To an extent, there is truth to this belief.  Cement can substitute for brick, and vice versa.  Renewable energy sources, such as wind and biomass, can substitute for coal and methane, which in turn can substitute for each other, at least by degrees.

But a few materials have such unique and essential characteristics that no matter how hard we try, no matter how much we innovate, no substitute can be found.
